Massive CPU frequency drop in my Acer laptop Aspire A715-75G

Hello everyone. I have a strange problem. I have an Acer Aspire A715-75G (8GB, GTX 1650, i5-10300H). Every once in a while, my laptop freezes for about 4 or 5 seconds and then returns to normal. When it freezes, background activity continues, but I can no longer do anything with my computer. I used the Windows Performance Recorder to investigate the problem. When that freezing problem occurs, even though my laptop is plugged in, the Windows starts using the battery (I'm not completely sure) and the CPU frequency suddenly drops to zero. I want to know if my laptop has a hardware problem or it's an OS problem? I bought my laptop a few months ago. I have reinstalled the Windows 10 and updated all drivers to the latest version. Any help would be appreciated💐

This is normal under heavy CPU/GPU load if the battery charge level while plugged in is allowed to drop below about 50%. Below that charge level, battery charging takes precedent over supplementing the charger to meet the heavy load CPU/GPU.

Accordingly, for maximum time under heavy loads, the battery should be near 100% charged and plugged in BEFORE starting the heavy loads in which both the battery and charger are supplying power to the CPU/GPU.

Thank you Jack. I mistakenly analyzed windows performance analyzer software data. My CPU frequency does not reach zero. When I stop recording the performance of Windows, the CPU frequency diagram automatically decreases, which actually indicates that nothing has been recorded since then. In fact, the problem with my laptop was the Babylon software, which is a famous dictionary for Windows users. Opening this software in Windows Ten is difficult. You must click on it a few times to open it. Windows has a function that sleeps open and unused programs in the background and puts them in the standby list and compresses them so that the system RAM has more space to run new software. Every once in a while, Windows calls them again to open them. Because Babylon software does not open easily, my PC was freezing for several seconds until the Babylon process is reactivated. After deleting the Babylon dictionary, the problem was solved.
